You creepy little stalker
I never look at user reviews to be honest.
First of all, they are hardly experts.
Secondly, they have likely bought the game, meaning that acts as bias. They bought it, so they throw in a few extra marks just because they bought it and don't want to be seen as owning a poor game.
Thirdly, most people that bought it/were given it probably didn't read the reviews, obviously. They are likely to be kids that don't have a clue about what makes a good game, due to the fact they were still in their dads scrotum when Sonic used to actually be good.
If you like it, fair enough, but user ratings mean very little to me without some sort of feedback system. You can usually tell if the user base is retarded by the posts they put up. If I see a post by people who have names like "supersaiyangoku13" who post stuff like "it iz wick£d, diss lets u be powerfool!" then I usually steer well clear.
